[T3] 2 cars 2 problems

Car 1 71 FI manual square.

It's running lean.  I suspect that it is air getting in the fuel lines.
When it hasn't been running for a while it takes a long time to start.
to test this I shorted the two connectors on the fuel pump relay under
the dash for about a minute before starting it.  Took off the short
and it started right up.  I stopped the car and shorted the relay
again to test the fuel pressure.  I noticed an odd sound coming from
the fuel pressure regulator.  The sound coming from it sounds when you
use your tongue to push some drool between your teeth.  Is this
normal or is it a sign of a LOT of air getting in the fuel lines?

The fuel pressure is 28.

I've replaced all the fuel lines at the back end of the car.  I plan
to replace the ones in the front when the tank is nearly dry.

Car 2 71 FI automatic square.

When I make a hard right or a fast right on a freeway entrance it
seems that the engine is cutting out.  I can't tell if it is ignition
of fuel.  I tried to duplicate it by jacking up the side of the car
with it running but I guess I can't get the side high enough to mimic
the centrifugal force that is causing the problem.  How to I find the
problem with this?
